My invention relates to a: tie plate and' has. for its primary object the; production ot atie plate haring an.y arrangement ribs'onthe under or' ti'e'eengagingsidethereofgwhich arey 5 so.: arranged; that the tie:v plate; seats; -rmfly` upon the; tie without cnttingfxthe surtacez libres n engagement with the tie underzthe rafih supe` porting surface of. thietieV plate so that the plate will nothave atendencyto shiiitr under:

transverselyv extending spaced@ ribs therenny on-- theA tre engagin g side thereot,z are positioned under' and/extend paraillehwitl'r space onl theundersideor1 thei plate. between the transverse ribsaand merge; into: said ribs at the sides thereof', wherehythe plate ,isanram terially strengthened *throughout the areas.: adjacentk thel transverse ribs on:v the inside thereof.

Another and further obieet ot myfinvention is the provision ot ati'ezplatehaving`- al. plurality oi triangular shaped recesses; formed?v inlI the body` thereofY betweenythetransverse ribs with'. their apexes. extending in opposite directions towards thev transverse ribs so that whenthe plate is embedded in the surface. ot the tie, movementof the plate inv endwise direction on the tie is;resisted;v` and the Yplate isy thereby secured 'toe the: tie. in ai.betterfmannerthan what hafsrbeenV possi hlewith tie platesr heretoiorex.-

thereof, withA af substantially uni-termi Another and'. further objectV of. myiirven:` tion `is the provision olta; tien plateharing;`

Itwill be understood that in. the manufac-` ture of the tie plates .the plates are rolled in continuous Stripspreerably inthe direction oftherail engaging ange, and thereafter this long plateis she'ared into lengths to forintie'plates.V It hasbeen extremely dilii'cult toY retain the proper thickness and surfacecontours of the. plates during both the rolling vand the shearingoperations because the plate: doesnot` cool uniformly, dueto? its unfeqgual thickness at various points, and also during the shearingoperations the cuttingV shear may bend or warp the plate, because in the arrangement-of the ribs the plate does notpossess uniform strain resisting qualities throughout ythe entire area kot thesection;

In .my improved form of tie plate the arrangement of. the ribs issuch that regardless of where the shear may pass through the plfatethe plate-tends to remain true to-gauge, andal will not easily be thrown out yot propert pla-neby the shearing operation.

Another and further object of my inven-l tion is-.theproyision of a tie rplate which is" lightinweight and yet possesses a maximum; amountof strength due to the distribution ot the metal in the plate and the arrangement o the ribs whereby the areas of the plate which aresubject tothe greatest stresses ared strengthened*7 with recesses formed in the body of the pla-te into. which the tie extends when the plate is inservice, so the plate is firmly seated on the tie.

Another and further object of my invention is thefprovision-of a tie plate having ribs thereonV which'extendparallel with the edges or the rail base and Vhave their maximum. thickness directly under the edges of ther-ail base where the strain is greatest, with the formation: ot connecting ribs preferably di'- agonally extending across the under surfaceof the plate between these two ribs, whereby the plate is braced inalongitudinal direction and: also is materially strengthened adjacent the ribs, the. connecting ribs forming recesses between these ribs which havetheir points extending both in inward andv outward direcf These and other objects of my invention will be more fully and better understood by reference to the accompanying sheet of drawin gs, in which-- Figure 1 is an end elevational view of my improved tie plate; and

Figure 2 is a bottom plan View of the tie plate illustrated in Figure 1.

Referring now specifically to the drawings c and in which like reference characters refer to like parts throughout, a tie plate 10 is shown having the usual transversely extending rail abutting flange 11 thereon and having the usual spikey openings 12, 12 therethrough, through which the spikes pass in securing the plate to the tie, the spikes having the usual heads thereon which engage the upper side of the rail base.

On the under surface of the tie platejand extending transversely thereof and parallel with the rail in spaced relation with each other, is a pair of ribs 13 and 14, the said ribs being adapted, on account of their rounded contour, to embed themselves into the tie without cutting the fibres thereof, with their deepest portions substantially parallel with the outside edges of the rail base. Intermediate the transverse ribs 13 and 14 and extending parallel therewith is a narrow rib 15 of less height than the ribs 13 and 14, and which' serves to strengthen the plate in the area between the transverse ribs 13 and underneath the web of the rail which the tie plate supports.

Extending' diagonally across the space in the bottom of the tie plate between the ribs 13 and 15, is a plurality of diagonally extending ribs 16, 16 which are merged together at their outer ends and into the side of the transversely extending rib V13, thereby strengthening the plate in the area adjacent the rib 13 on the inner side thereof and forming a plurality of triangular shaped recessed areas 17, 17, the bases of these triangular recessed areas being adjacent the rib 15, while their apexes extend outward towards the rib 15. A plurality of other recessed areas 18, 18 are also formed by the ribs 16 which have their bases extending parallel with the rib 13, with their apexes extending inwardly towards the rib 15 and terminating adjacent thereto. On the opposite side o-f the rib 15 in the space between the said rib 15 and the rib 14, is aV plurality of other diagonally extending ribs 19, 19 arranged in the same manner as the ribs 16. 16 at the opposite side of rib 15, and which form triangular shaped recessed areas 20 and 21 respectively which have their bases against the rib 15 and the rib 14 respectively.l with their apexes extending in opposite directions so that the plate adjacent the rib 14 is strengthened both against bendin g and also against a twisting movement.

' When the tie plate is placed upon a tie and into engagement with the surface thereof, movement of the plate is resisted because of the engagement of the ribs 16 and 19 respectively in the fibres of the tie, in addition to the resistance afforded by the ribs 13, 14 and 15. Because the tie plate is firmly held in engagement with the tie, the channels formed in the tie by the ribs 13 and 14 will not become enlarged, as is common with tie plates of the present construction. This movement will also be iesisted by the diagon'ally extending ribs 16 and 19 because these ribs will have embedded themselves in the tie, and the triangular shaped portions of thetie which fit into the recesses 17, 18, 20 and 21 will serve to hold the tie plate in proper relation with the tie to prevent a turning movement and also to prevent slippage of the tie plate upon the surface of the tie. The triangular shaped recesses receive similarly shaped portions of the tie when the tie plate is placed in service upon a railway tie for the purpose of preventing the skewing around of the tie plate under the rail.

It will be understood that the surfaces of the recessed areas extend slightly into the body of the plate, and that these recesses are not formed merely by the diagonally extending ribs. In the manufacture of the plate the ribs 15,16 and 19 are formed ofthe inet-al lying in the area between the ribs 13 and 14, so that in effect a portion'of this metal is removed to form the ribs 16 and 19 respectively, resulting in the production of a tie plate having strengthening ribs extending diagonally across the area between the tie engaging ribs 13 and 14, with the recesses being formed in the body of the plate, so

that the entire area under the rail base is stifened or braced by these ribs, with recesses being formed in the bottom of the plate in such manner that it engages the tie without slipping or without mutilation of the fibres of the tie and the destruction of the tie itself, so that long life is accorded the tie and maximum support provided for the rail with a minimum of weight in the tie plate. I may find it expedient to omit the rib 15 in the manufacture of the tie pla-te, and the direction and arrangement of the strengthening ribs may be also slightly altered, if desired. l

While I have described more or less precisely the details of construction, I do not wish to be understood as limiting myself thereto, as I contemplate changes in form and the proportion of parts and the substitution of equivalents as circumstances may suggest or render expedient without departing from the spirit or scope of my invention,
